Print Screen Boot
This is a very small virus that stores the original boot sector in the last sector of the root directory, just like the Stoned and Korea viruses. It relocates the original INT 13 to INT 6D, which will cause problems with many VGA cards. As the name indicates, the virus will occasionally perform a PrintScreen operation.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
